Once reserved for jogging or hitting the gym, track pants are having a cool fashion moment and it's thanks in part to designers like Tory Burch, Versace and Rag & Bone sending them down their fall/winter 2016 runways.

Stylish stars like Olivia Palermo, 30, Rosie Huntington-Whiteley, 29, Bella Hadid, 19, and Lily Aldridge, 30, have taken notice and have all incorporated the sporty trousers into their chic polished looks recently.

BOARD MEETING: If anyone can make track pants office-appropriate, it's Rosie. Cop her look and find a tailored blazer in the same colorway as the loose trouser. Finish with a classic satchel and killer heels and show 'em who's boss.

DINNER WITH FRIENDS: Olivia elevated the feel of her sporty bottoms with dressy separates. To re-create her chic ensemble, team a sleeveless turtleneck with a billowy top. Accessorize with a sleek choker and pumps and you're ready to hit the latest hot spot.

'It' girl: Olivia Palermo, 30, hit LFW this week in a pair of Zara track pants paired with a Rebecca Minkoff long sleeved top layered under a sleeveless turtleneck

DATE NIGHT: Leave it to Lily to make activewear look sexy. For a night on the town, show a little skin by pairing athletic pants with a sleeveless top. Add some height with strappy stilettos and complete the outfit with a simple jewels and a chic clutch.

Top model: Lily Aldridge, 30, paired her stylish track pants by Chloe with a silk tank and modern accessories

CASUAL BRUNCH: When it comes to weekend wear, comfort is key. Take the fuss out of getting ready and throw on a full track suit like Bella. To avoid looking like you just rolled out of bed, slip into a pair of heels and slide on a pair of sleek shades.
